VENTILATED URINAL.

SPECIFICATION forming part of Letters Patent No. 519,355, dated May 8,1894.

Application filed September 2,1891- Serial No. 4 4|4=88- (No model.)

To aZZ whom, it may concern.-

Be it known that I, FRED P. SMITH, of the city and county of Worcesterand State of Massachusetts, have invented certain new and usefulImprovements in Ventilated Urinals; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, ref erencebeing had to the accompanying drawings, forming a part of thisspecification, and

to in which Figure 1 represents a vertical, longitudinal section takenat the point indicated by line a a in Fig. 2, looking in the directionof the arrow same figure, showing, partlyin section,

and partly in elevation, one end of a series of ventilated, urinalcompartments, arranged side by side, as will be hereinafter more fullydescribed. Fig. 2 is a vertical, transverse section, taken at the pointindicated byline b b in Fig. 1, showing a double set of ventilatedurinals, arranged back to back at a short distance apart over the usualventilating duct. Fig. 3 is a similar view to Fig. 2 showing a vertical,transverse section through 2 5 a single set of ventilated urinalsarranged above the usual ventilating duct, against a wall or partition.Fig. 4 is avertical section on line 0 Fig. 2. Fig. 5 is a horizontalsection on line d Fig. 2, and Fig. 6 is a vertical sec- 0 tion on linee, Fig. 2; all of the last three figures being upon an enlarged scale,to more fully illustrate the construction.

My invention relates to slab urinals for school and other publicbuildings, and its ob- 3 5 j eat is to provide better ventilation at orabout the fouling point, and at the floor of said urinals, as well as animproved construction, whereby the Various slabs or partitions andflooring composing the urinal stalls or com- 0 partments may be fastenedtogether more conveniently, and at less cost than heretofore.

Said invention consists in making the back of each urinal compartment intwo pieces, one above the other, with the bottom edge of 5 the upperpart overlapping and at a short distance out from the upper edge of thebottom part so as to form a ventilating opening between said twooverlapping edges, at or about the level of the fouling point.

It also consists in forming a ventilating opening at the outer edge ofthe floor slab in addition to the usual ventilating opening at the inneredge thereof, and it furtherconsists in forming suitable grooves in thetop slab,

the vertical, transverse partitions and the floor slab, so that thevarious parts may be readily fitted together in said grooves, andsecurely held in position without the use of clamps, angle-irons orother usual fastenings, as hereinafter more fully set forth. s

In order that others may better understand the nature and purpose of mysaid invention, I will now proceed to describe it more in detail.

In practice, as is well known, urinals of the class to which myinvention relates, are dividedinto a series of compartments arranged ina row,side by side, either single or double, as previously stated; butfor convenience in illustration I have shown only one completecompartment A, and parts of two others, B, O, in Fig. 1 of the drawings.Said series of compartments consist of the transverse, verticalpartitions D; the top, horizontal slab E; the vertical, longitudinalslabs or back pieces F, F, which are preferably inclined slightly,

and the floor-slab, or slabs, G, the latter, for

greater strength being preferably thicker than the others as shown. Saidslabs may be made of slate, marble or any other suitable, analogousmaterial, and supported as usual. They are constructed, arranged andfitted together as follows: .The top and bottom pieces, E, G, which arein practice preferably made in one continuous length, are both groovedtransversely, on one side, the top piece upon its under side to receivethe top edges of the transverse or cross-partitions D, and thefloorpiece upon its upper side to receive the bottom edges thereof, asis indicated at fin Figs. 4 and 5.- Said transverse or cross-partitionsare also each made in one piece and their sides grooved vertically, toreceive the side edges of the back pieces F F, as is shown at g g inFig. 6, and by Figs. 1 and 3. The back pieces F are made of the properlengths to to bring their lower ends down to about the level of thefouling point, while the bottom pieces F extend up back of, at a shortdistance from and just above the bottoms of said top, back pieces F, asis shown in the drawings; thus providing a ventilatin g opening ha-crossthe back of each urinal compartment into the usual ventilating space i,back of the fouling surface, in addition to the usual top and bottomventilating openings j, 70. I also provide in addition to said usualopenings j is, a ventilating opening Z, at the outer or front edge ofthe floor-slab G, between the same and the edge of the floor, connectedby the space m under said slab, with the usual ventilating duct H. Thespace back of the urinals also being connected therewith, as shown inFigs. 2 and 3 of the drawings. Said duct H not only serves as a vent,butalso as a trough to carry off the urine discharged therein from theurinals above, being provided with a cement, metal or other suitablelining n. It is connected in practice with a suitable ventilating stackor shaft extending up through and above the building in which theapparatus is placed, whereby a strong draft is maintained downward fromthe urinals, as is indicated by the arrows, but as said stack or shaftand connection constitutes no part of my present invention, it is deemedunnecessary to illustrate the same.

The essential features of myinvention are, first:the means ofventilation at the fouling point; second:-the means of ventilation atthe outer edge of the floor-slab, and third the mode of constructionwhereby the different parts may be fitted and fastened together quicklyand securely without the use of the fastening devices ordinarilyemployed.

It will at once be apparent that by thus providing the urinals with aventilating opening at or about the level of the'fouling point, as wellas at the outer edge of the foot-slab, in addition to the usualventilating openings aforesaid, the air in the compartments and aboutthe same may be kept comparatively pure, and free from the usualoffensive and injurious properties emanating from this class of urinals.It is also obvious that a series of urinals constructed in the mannerherein shown and described, may be fitted and fastened together in avery easy and expeditious manner; and when thus united are held socurelyfrom displacement. Then, again, by making the joints as aforesaid, atighter fit may be obtained, and the whole series of urinals,furthermore, present a neater and more tasty appearance than by the oldmethods of construction and fastening.

I reserve the right to apply my invention to either a single row orseries of urinals arranged against a wall or partition, as shown in Fig.1; or, a double row arranged back to back, as indicated in Fig. 2.

What I claim as new, and desire to secure by Letters Patent, is

1. In slab urinals, the backs thereof made in two parts F F arranged oneabove the other and the upper part overlapping the lower one with ashort space between their overlapping edgesto form a ventilatingopening, h horizontally across said backat or about the level of thefouling point, substantially as and for the purpose set forth.

2. In slab urinals, the combination of the back, the dividing partitionsbetween the stalls or compartments and the floor, with the bottom orfloor slab G made of the proper width and arranged to form longitudinalVentilating openings at both its front and back edges communicating withthe main ventilating duct H, substantially as and for the purpose setforth.

3. In slab urinals, the combination of the top and bottom horizontal,longitudinal slabs E, G, and the usual division partitions, with theback made in two parts F F arranged one above the other and the upperpart overlapping the lower one with a short space between theiroverlapping edges to form a ventilating opening it horizontally acrosssaid back at or about the level of the fouling point in addition to theusual top and ventilating openings j. lasubstantially as and for thepurpose set forth.

4. In slab urinals, the combination of the top slab E, the usualtransverse division partitions and the fioor with the back made in twoparts F F one above the other and the upper part overlapping the lowerone with a short space between their overlapping edges .to form aventilating opening it horizontally across said back at or about thelevel of the fouling point in addition to the usual top and bottomventilating openings j k, and the bottom or floor slab G made of theproper width and arranged to form alongitudinal ventilating opening Z atits outer edge between the same and the floor in addition to the usualventilating opening it at its inner edge, substantially as and for thepurpose set forth.

5. In slab-urinals, the combination of the horizontal top piece E havingtransverse grooves therein to receive the upper edges of the vertical,transverse partitions D 3 the bottom, horizontal piece G, havingtransverse grooves therein to receive the bottom edges of the transversepartitions; said transverse partitions having substantially verticalgrooves in the sides thereof to receive the side edges of the backpieces F F and said back pieces arranged between the transversepartitions with the upper one overlapping the bottom one at a shortdistance apart, substantially as and for the purpose set forth.

6. Inslab urinals, the combination of the back forming the foulingsurface, and the floor, with the bottom or floor-slab G made somewhatnarrower than the space between said back and the edge of the floor infront thereof, and arranged to form a longitudinal, Ventilating openingZ at its outer edge between the same and the floor, in addition to theusual ventilating opening at its inner edge, and communicating with themain ventilating duct H, substantially as and for the purpose set forth.
